Inventor: EHWALD RUDOLF
IPC: C12N11/16
Filed: 1988-06-07
Abstract: A hollow carrier of plant origin 15 filled with living or permeabilised enzymatically active microorganisms or with enzymes. The biocatalysis module consists of an extracted intact plant or an extracted intact plant part with an air-filled tissue rich in intercellular spaces, namely the aerenchyma, which is outwardly limited by a sealed barrier tissue with hydrophilic cell walls, and contains cells or enzymes of a foreign organism. The method for producing the biocatalysis module consists in that foreign cells or enzymes are absorbed into the aerenchyma of an extracted uncomminuted plant or of an uncomminuted plant organ through an open connection or introduced therein by means of injection. Aerenchyma-rich strip-shaped or cylindrical plant bodies enable the hitherto unknown introduction of cell-free enzymes into a plant hollow carrier, e.g. into aerenchyma-rich lyophilised and extracted roots.

Patent DE-3834796-A1 (DE)
Inventor: PAINTNER HERMANN
IPC: A01D27/04
Filed: 1988-10-12
Abstract: In hitherto known beet-harvesting machines, sensors which sense the ground serve for the depth control of the digging unit. A disadvantage of these is the relatively high sensitivity, since incorrect signals for raising the digging share are obtained even in the event of insignificant clods or accumulations of weeds. According to the invention, for the depth control of the digging share (30) of the digging unit (28) there are feeler wheels (48) which are mounted on a common shaft (50) and which are vertically adjustable in relation to the digging unit (28). The digging unit (28) can itself be adjusted vertically and horizontally relative to the leaf-cutting unit (24), since it is suspended on the chassis of the device so as to be angularly movable. <IMAGE>

Patent DE-3903714-A1 (DE)
Inventor: TOBITA YOICHI
IPC: G11C29/46
Filed: 1989-02-08
Abstract: In a semiconductor memory device having a test mode setting circuit, when a voltage higher than a common operation range is applied to an input terminal (101) receiving +E,ovs CAS+EE  signals, a first voltage detecting circuit (100) detects the voltage and the detected output is latched in a latch circuit (110). A voltage setting circuit [(1 20)] (120) sets a cell plate voltage of a memory cell [(1a)] (1) approximately at the ground potential in response to the latch output. Consequently, the operation margin of the memory cell for the data "1" can be carried out by the V bump test. Meanwhile, when a voltage higher than the normal operation range is applied to an input terminal (201) receiving +E,ovs WE+EE  signals, a second voltage detecting circuit (200) detects the voltage and the detected output is latched in the latch circuit [(201)](210). The voltage setting circuit sets the cell plate voltage approximately at Vcc in response to the latch output from the latch circuit.

Title: Electronic analog slave clock (secondary dial) with hand lengths of up to 600 mm
IPC: G04C13/08
Filed: 1989-06-08
Abstract: Electronic analog slave clocks of this order of magnitude generally require for the purpose of incrementing the time of the clock hands an additional energy source which renders the design of the slave clock system complicated and more expensive. The object of the invention is to eliminate energy-consuming dial train mechanisms with the aim of gathering the energy requirement for incrementing the clock hands exclusively from the pulse level of a seconds slave clock line. The problem is solved by means of an axial and sliding contact system according to Figure 4. Via the tube axis (7) which is firmly seated in the baseplate (1), the pulse line is electrically connected to the contact slide rings (11) and (12), which are assigned in pairs and via contact springs feed the seconds pulses to the sequence processors (step-by-step systems, intermittent motions) which are integrated in the ball-bearing-mounted clock hands and, for their part, are driven by the known principle of gravitational force. Electronic analog slave clocks of this design are suitable for use in industrial halls, market halls (covered markets) and sports halls, in office and school buildings, clinics and railway stations. <IMAGE>
